The documentation at http://doc.akka.io/docs/akka/snapshot/scala/cluster-usage.html doesn't state that the PoisonPill performs differently than the behaviour listed here <http://doc.akka.io/docs/akka/snapshot/scala/routing.html#note-router-terminated-children-scala>, so I assumed if I used a Broadcast message like below:
... def vectorizeUserContent(streamer : ActorRef, libraryId : Long, senderNode : ActorRef) = { val userVectorizationReducers = context.actorOf(FromConfig.props(Props[ UserVectorizationReducer ]), "userVectorizationReducer") context.actorOf(Props(new Actor { override def preStart() { context.watch(userVectorizationReducers) streamer ! StartStream(libraryId) } override def receive = { case dto : RawUserContentDto => userVectorizationReducers ! ConsistentHashableEnvelope(dto, dto.userId) case EndOfStream() => { userVectorizationReducers ! Broadcast(ReturnUserVectors(senderNode)) *userVectorizationReducers ! Broadcast(PoisonPill)* } case Terminated(userVectorizationReducers) => { senderNode ! VectorizationCompleted() self ! PoisonPill } } }), "userContentVectorizerDirector") } ... where userVectorizationReducers is a remotely deployed pool of routees, the Terminated message would be retrieved due to the watch made in preStart(). Unfortunately, the broadcasted PoisonPill does not trigger the expected Terminated message I'm waiting for. If I however replace the broadcast in my 'EndOfStream()' case with userVectorizationReducers ! PoisonPill, then the Terminated message is returned. In both cases, all routees are terminated individually (evident through some logging in the postStop() method of the UserVectorizationReducer actor). I'm assuming the PoisonPill is actually being routed to the routees where they can be gracefully shutdown after all other messages have been processed, but I could be wrong. Can I get clarification if this is in fact true and it is the recommended way to shutdown a pool of cluster routees?
